3. 3 OBJECTIVES To assess their suitability inroad construction on the basis of impact value. This test is done to determine the aggregate impact value of coarse aggregates. Many tests have been developed toempirically characterize aggregate properties without, necessarily, strong relationships to the performance of final products incorporating an aggregate.
